Abstract

The present invention relates to an insect protection door with a door closer in particular, but also to doors in general, which can be operated on one side and on both sides, the insect protection door or door having a hollow profile (2) surrounding the pivot bearing axis (1) and two bearing blocks (4) with bearing journals (5) and one on the bearing pin (5) acting as a torsion spring bearing receiving groove (13) as well as at least one torsion spring (3) and at least one torsion spring bearing block (7), the hollow profile (2) being partially designed as a polygonal tubular profile, and where an inner profile (8) is designed as a polygon with circular bulges (9). The hollow profile (2) partially has an extension (10) for fastening doors (11) of any kind. The bearing blocks (4) each carry a bearing pin (5) which has the receiving groove (13) for the torsion spring (3) in one axial direction. In its angular part of the inner profile (8), the hollow profile (2) takes the at least one torsion spring bearing block (7) which is connected to the bearing journal (5) via the torsion spring (3). The invention creates an insect protection door with low manufacturing costs, high ease of assembly and operation, and an attractive appearance.

Description

Insect protection doors are used to protect buildings or people in them from insects. As a rule, they are not installed during the construction phase, but rather when a building is already inhabited, in front of or in architectural openings. A frequent disadvantage of commercially available insect protection doors is that they can only function in conjunction with a door frame. The automatic closing is effected with torsion springs which are integrated in the door. As a result, the door has to be mechanically connected to an additional door installation frame on which the torsion springs are supported. The bearing shells for the pivot bearing of the door are also attached to the installation frame. This restricts the use in practical operation. In addition, the assembly and disassembly of the insect protection doors, which are expediently only used in summer, is not easy. It has to be easy, however, as the door must be able to be fitted and removed seasonally by people who have no special tools, no knowledge of the function and no time (desire) to delve into the subject. In addition, the unsightly torsion springs are visible and cause unpleasant noises when they come into contact with the door frame.

Insect protection doors that deal with these problems are, for example, from DE 78 34 765 U1 or the DE 10 2010 053 415 A1 known. The subject matter of both publications, however, has in common that, due to their design, they have a wide hinge or rotating device mechanism, which not only reduces the usable width of, for example, doors, but is also not very visually appealing.

Proceeding from this, the invention is based on the object of further improving the devices known in the prior art and of making them producible with the least possible manufacturing effort, high ease of assembly and operation, and an attractive appearance.

To solve this problem, the combination of features specified in the claims is proposed. The invention relates to an insect protection door, which can be operated both on one side and on both sides, with or without a door installation frame, with a door frame for mounting an insect protection grille and a door closer with rotary bearing blocks. The door frame is attached to the stationary door closer and together with it forms an autonomous, easily separable unit, which can be attached to any opening without having to constructively prepare the edge of the opening. The door closer has a hollow profile surrounding the pivot bearing axis, at least one torsion spring, two bearing blocks ( 4th ) with trunnion ( 5 ) and in each case a receiving groove acting as a torsion spring bearing on the bearing journal and at least one torsion spring bearing block.

The insect protection door according to the invention according to claim 1 is characterized in that it can be attached anywhere (stationary objects, moving objects). It is also characterized by the fact that it can be used to operate any door for any application. Another advantage of the invention is that it can be attached and fastened to the opening to be closed by the door (e.g. on the patio door) without any structural preparatory work on it. A particular advantage of the construction according to the invention is that it is suitable for doors that can be operated on one side as well as for doors that can be operated on both sides (e.g. swing doors). The automatic door locking device is optional and can be designed to act on one side or on both sides. What is very important is the property of the invention that the doors that can be operated with it can be opened beyond the closed position on both sides by well over 90 degrees. The construction also gives each door an attractive appearance.
